And the coordinator exhales. Good visit. No problems.

But here is what I want you to notice about that interaction. The entire quality conversation happened after the fact. The work was done weeks or months ago. The monitor arrived, looked backward through that completed work, and rendered a verdict. The coordinator's definition of quality was, in essence: did someone check my work and find it acceptable?

This is retrospective quality control. And for decades, it was the dominant model in clinical research. Quality meant inspection. Quality meant someone else--a monitor, an auditor, a sponsor representative--looking at finished work and deciding whether it passed. The coordinator's job was to do the work. Someone else's job was to check it.

ICH E6(R3), finalized on 6 January 2025, says this is not good enough. Not because monitors are unnecessary--they are not going anywhere. But because a model built entirely on after-the-fact inspection is structurally inadequate for protecting participants and ensuring data reliability. The new guideline introduces something fundamentally different: the expectation that quality is designed into clinical trial processes before the work begins, not verified only after the work is complete.

This distinction--between finding problems and preventing them--is, in my view, the single most consequential shift that E6(R3) introduces for the daily work of clinical research coordinators.
